ELECTRIC SWITCH.

SPECIFICATION forming part of Letters Patent No. 713,133, dated November 11, 1902.

Application filed March 13,1902. Serial No. 98,032.

To all whom it may concern.-

Be it known that I, TAGE MULLER, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, (whose post-office address is 39 Oortlandt street, in the said city 0f New York,) have invented certain new and useful Improvements in Electric Switches, of which the following is a specification.

My invention relates to fluid-operated electricswitehes,and is moreparticularlydesigned as an improvement upon the invention set forth in Letters Patent No. 656,716, dated August 2S, 1900.

In the above-mentioned patent a'fiuid-actuated melnber is used to operate a tilting weight to either open or close the switch on a quick action.

In the present invention, atilting weight is attached to or moves with the movable electrode, there being a second tilting weight, which is movable independently to operate the movable electrode, caused to act by means of a fluid-actuated member.

The object of my invention is to obtain more positive results on the quick-action movement to open or close the switch; also to do away with springs or similar device for holding the movable electrode in its open position. These objects I attain bythe abovementioned means, which are more particularly described hereinafter.

I shall describe a Huid-actuated switch embodying my invention and afterward point out the novel features in the claim.

In the drawings I have embodied my invention in what I consider a preferable form; but changes may of course be made within the scope of the claim.

In the said drawings, Figure lis a side view in section of a fluid-actuated electric switch embodying my invention. Fig. 2 is an enlarged top View of Fig. 1 with parts broken away.

Similar letters of reference indicate corresponding parts in the different views.

The detailed construction of the old part of the switch will not be described, as it is well known in the art, a full and complete descrip- (No model.)

tion of same being found in Letters Patent No. 656,716 referred to above.

A is the Huid-actuated member caused to move vertically by the inflatable diaphragm a' or other means and provided with the shoulders a2 and a3 at its upper end.

Bis the stationary electrode, and O the movable electrode. The latter is carried by the arm c' and secured to the tilting weight D, which in turn is mounted fast on the transverse pin c2, mounted in the lugs c3. The weight D consists in this instance of a narrow upright portion LZ', fastened to the pin o2 Vby means of the screws d2, and an arc-shaped portion d3, fastened to the upper end of the upright portiond.

E is a second tilting weight 1n ountedloosely upon the pin e2 and movable independently of the weight D and electrode O. This second tilting weight is quite heavy and is provided with a longitudinal slot e, separating it into two parts e2 and e3, joined at one end by the bridge portion e4 and further carries a transverse pin e5. Owing to the slot e', the weight E is free to move without touching the weight D, the upright portion CZ/ of which extends up 'through the said slot.

When the switch is in the position shown in Fig. 1 and the air-pressure then decreases, the member A will descend, and the shoulder CL3 will coact with the transverse pin e5 and slowly move the weight E until it is past the center, when it will descend quickly by reason of gravity on the arm c', thus bringing the weight D over the conter, thereby moving both weights and increasing the momentum and in that manner insuring a positive quick action. When the pressure increases, the member A will rise and the shoulder 0,2 will push the pin e5 slowly up, thereby moving the weight E until it passes-over the center and drops, with the portion c, on the arm c', thus bringing by the cooperation of the weight D the electrode() quickly out of contact with the stationary electrode B. The arm c is provided with a pin 010, which rests upon the stop c, thus limiting the movement. No spring detention device is necessary to hold the movable electrode in its open position, as the Weight D will be sufficient to keep it in its properv position unadapted to operate the rst-mentioned tilttil the Weight E operates to close the switch. ing weight and movable electrode on a quick l Having thus described my invention, what action. i 5 f d 5 I claim is- Signed at New York, in the county of New /4 `In an electric switch, the combination with York and State of New York, this 10th day of a stationary electrode and a uid-actuated March, A.
